OTTO-VON-GUERICKE-UNIVERSITÄT MAGDEBURG Fakultät für Verfahrens- und Systemtechnik Institut für Apparate- und Umwelttechnik ROLE OF HYDROGEN The scarceness of fossil fuels and the resulting price increases have put alternative energies on the agenda. Hydrogen: may play an important role enables one to store energy and put it into end use at the time and place desired production sources: electricity (nuclear energy), renewable energy sources (wind, sun), electricity produced during hours of low consumption by a country’s electric power system A large-scale introduction of hydrogen into an economy requires that the risks associated with it should be at least not higher than those of existing technologies, e.g. LPG 1.

OTTO-VON-GUERICKE-UNIVERSITÄT MAGDEBURG Fakultät für Verfahrens- und Systemtechnik Institut für Apparate- und Umwelttechnik 1. Introduction 2. H 2 Economy 3. Methods 4. Example 5. Risk 6. Conclusions CONCLUSIONS 1.Risk of the hydrogen economy is not higher than that of a competing option, namely LPG. 2.Risk of the storage of gaseous hydrogen under pressure analysed here is low and can be tolerated, if current international risk objectives, i.e. individual risk around 10 -6, are used as a yardstick. 3. There is no obstacle from the perspective of safety to implementing a “hydrogen economy”
